Mission of the I-70
Silverthorne/Dillon Interchange Project Leadership Team
The mission of the I-70 Silverthorne/Dillon Interchange Project
Leadership Team is to deliver a multi-modal transportation project that
is a model for the I-70 Mountain Corridor. We will respect community
and environmental values while improving safety and mobility by
engaging in an inclusive and transparent process that is widely
supported and manages expectations. The PLT will champion the CSS
process and demonstrate best practices in all respects.

Established Goals
for the I-70 Silverthorne/Dillon Interchange Project
The Colorado Department of Transportation (CDOT) will conduct a study
of potential improvements to the Interstate 70 (I-70) interchange with
U.S. Highway 6 (US 6) and State Highway 9 (SH 9), located in the Town
of Silverthorne. The mission is to deliver a multi-modal transportation
project that is a model for the I-70 Mountain Corridor. Beginning
in September 2010, the project will evaluate and recommend for further
consideration alterative options that achieve the following preliminary
or draft goals:

To deliver a project that is a model for the I-70 Mountain Corridor
by enhancing mobility -- including multi-modal transportation system
performance improvements -- while highlighting a successful
collaboration between the Federal Highway Administration (FHWA), CDOT,
and local agencies, as well as how value may be generated from the
Programmatic Environmental Impact Statement (PEIS).

To develop an innovative interchange solution that is of
appropriate scale; respects community values and environmental
resources; meets all of the various stakeholders’ needs; and is
consistent with adopted local plans, policies, and economic development
objectives.

To embrace the I-70 Mountain Corridor Context Sensitive Solutions
(CSS) decision-making process while adhering to the overall corridor
vision and core values. The project will demonstrate best practices in
all respects.

To allow inclusive and transparent stakeholder involvement in the
development and selection of alternatives facilitated by a strong,
long-term intergovernmental team that manages expectations and allows
“no surprises” so that the resulting project can be endorsed and
“owned” by the community.

To improve local traffic flow on U.S. Highway 6 (US 6) and State
Highway 9 (SH 9) and regional traffic flow on I-70, US 6, and SH 9,
minimizing regional travel times while improving access to major
activity centers and providing the appropriate balance of through
traffic and local access needs with a long-term transportation vision
in mind.

To include, consider, or not preclude future transit improvements
-- including an Advanced Guideway System alignment and possible transit
station.

To improve safety for motorists, transit riders, cyclists, and
pedestrians within the project limits.

To identify, where possible, public and private-sector partnership
opportunities to address aesthetics, access, maintenance, local road
improvements, and private improvements.

To define flexible alternatives for interchange phasing, including
early action opportunities, that can be built either in whole or in
logical phases consistent with available funding and prioritized
needs

To avoid, minimize, and mitigate adverse impacts to the local
businesses and surrounding environmental resources -- ultimately
improving existing conditions -- consistent with the intent of the CSS
process and CDOT’s policies and practices. This will be a
“self-mitigating” project, which builds the mitigation into the
solution.

To deliver a project that is economically and physically
feasible.

To incorporate sustainability principles and practices into the
decision-making process and the design and construction of future
improvements.
